A sheet member conveyance device includes: a support part configured to support a sheet member; and a moving part configured to move the support part to convey the sheet member, the support part including a deformation support part configured to support each of one end portion of the sheet member and another end portion of the sheet member, which are opposed to each other, and to partially deform the sheet member into a curved shape, to thereby form a convex thread portion or a concave thread portion crossing a principal surface of the sheet member.

The invention relates to a device for unwinding a coil of a metal strip including a bogie translatable back and forth along a guiding system; a blocking system which is arranged on said bogie and which contains a first and a second shaped element, wherein the first shaped element is a roller, preferably an idle roller; an actuating system for modifying the distance between the two shaped elements, for defining an intercepting position and a gripping position of the strip; and an element for detaching the strip from the coil provided on the first shaped element. A relative method of unwinding and inspecting a metal strip is also described, in particular used to check the state of wear of rolling cylinders used for producing the inspected strip.

A main object of the invention is to provide a sheet material separation-aiding apparatus that ensures that there can be a gap produced stably between a specific sheet material from a stack of sheet materials and a sheet material just below it, and that achieves size reductions, reduced energy consumptions and a decreased parts count. As shown in FIG. 4, the sheet material separation-aiding apparatus 1 comprises a rotating means 2 including an abutment portion 21 that is capable of coming in abutment on an end of the uppermost sheet material 101, a supporting means 3 that supports the rotating means 2 in a rotatable manner and is capable of moving in a vertical direction, a biasing means 4 that biases the supporting means 3 in a downward direction, and a lifting means 5 that lifts up an end 23 of the rotating means 2 in opposition to the abutment portion 21. As the end 23 is lifted up, it causes the rotating means 2 to rotate with the abutment portion 21 coming in abutment on the end of the sheet material 101, and as the end 23 is further lifted up, it causes the supporting means 3 and rotating means 2 to keep on going up while the rotating means 2 is kept from rotation by a counterforce that the abutment portion 21 receives from the sheet material 101.

The device for handling adjacent sheet elements comprises a clamp (2) for gripping a sheet element (10) and a capture head (1) which is provided with clamping means (4), which separates, grips and lifts an edge of a sheet element (10). The capture head/s (1) is/are rotatable about a longitudinal axis (3).

It allows the handling of sheet elements consisting of one or more layers of sheet material, allowing the clamp to slide along the surface supporting the elements to access the underside of the sheet element, thus capturing the elements on the same surface that has been used to cut them.

A winding apparatus for secondary batteries includes a first clamp having a first contact portion to be in contact with a separator in a longitudinal direction, a second clamp having a second contact portion to be in contact with the separator in the longitudinal direction, the second contact portion being configured to be engaged with the first contact portion while the separator is therebetween, blades surrounding the first clamp and the second clamp, the blades being configured to allow the separator to be wound therearound, and a driver configured to move the first clamp and the second clamp toward each other and away from each other.

A device for handling elements comprises a shank provided with a stop; a rod which is longitudinally movable and rotatable with respect to the shank, comprising a flap at one end thereof, so as to define a clamp between the stop and the flap for gripping an element. A method comprises placing elements separated by at least one slit on a surface; inserting a tip of a shank provided with a flap inside the slit; placing a stop in contact with an upper part of the element; rotating the shank, holding the element on the upper part by the stop and on a lower part by the flap; and separating the element.

A gripper is for holding and depositing a stack of sheet material at a depositing location, and has at least one first gripping element, which comprises or forms a first contact surface for contact with the stack, and at least one second gripping element, which includes a second contact surface for contact with the stack. The first and second contact surfaces are designed for contact with the stack on both sides. The gripping elements are guided adjustably with respect to one another so that the contact surfaces can be moved with respect to one another in the direction of the surface normals that are respectively associated with the contact surfaces to hold the stack between the contact surfaces. The first gripping element is mounted to pivot about a pivot axis so it can pivot between a gripping position, and a release position.

To downsize a curved transport route through which a transport target is transported without being deformed. A transport path 401 includes a first curved transport tubular-body unit 415B having a first curved shape in which a bottom surface 411B located beside an air blowing tube 100 bulges into a convex shape toward the air blowing tube. The first curved transport tubular-body unit is configured to increase a distance H between the bottom surface and a top surface 413B opposite to the bottom surface from each end portion toward an intermediate portion in a transport direction x to prevent a banknote P retained by a transport body 500 from coming into contact with the top surface.

A tape supply device is disclosed. The tape supply device comprises a supply roll supplying a tape having a first surface and a second surface formed opposite to the first surface; and a clamp gripping an end of the tape drawn from the supply roll. The clamp includes a first fixing part movable in an up-down direction, the first fixing part positioned above the tape, the first fixing part facing the first surface; a second fixing part positioned below the first fixing part, the second fixing part positioned below the tape, the second fixing part facing the second surface, and the second fixing part movable in the up-down direction, the second fixing part including a through hole; and a push rod positioned below the second fixing part. When the second fixing part moves down, the push rod passes through the through hole and protrudes upward from the second fixing part.

Embodiments relate to a jelly roll winding unit (1) and winding method for a secondary battery and, more particularly, to a jelly roll winding unit (1) and winding method for a secondary battery seeking to prevent sagging in the width direction by constantly supporting the bottom of a jelly roll (J) during the work of wrapping the jelly roll (J) with a separator (B) and easily guides the folding line of the separator (B) as needed.
